Abstract: A medical instrument includes an apparatus for detecting activation cycles of the instrument. First and second parts of the instrument are movable relative to each other in an activation cycle. An energy detection coil detects inductively generated energy. An energy-generating magnet inductively generates energy to be detected by the energy detection coil. In the event of movement of the first movable part and the second movable part relative to each other, the energy-generating magnet is movable in a detection region of the energy detection coil and induces energy. A memory and processing device has a counter, detects a voltage signal based on the induced energy during each relative movement, increases the counter by one for each detection of the voltage signal, and counts the number of activation cycles of the instrument. In an alternative embodiment, the voltage signal is generated using a voltage created by a piezoelectric element.
